You can't upgrade from CentOS 5.6 to CentOS 6.0.
Rather you would need a fresh installation of CentOS 6 and migrate your data to new server.

It is possible but Red Hat (Centos is a mirror replica of Red Hat) does not recommend doing it.
See here
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/ch-upgrade-x86.html
There are some people who have done it though.

The best idea is to backup your system and reinstall.
- Backup /etc completely.
- Run this command "chkconfig --list | grep :on" list all the active services.
- Transfer /etc backup to the new system and open it to another location.
- Install the new system then install all the packages required using the list.
- Replace the config files from the /etc backup
- Check the old system fore iptables rules adn SELinux if enabled adn apply same rules to the new system.

Cheers,
